Claiming a VAT refund for excess input tax
When a Kenyan exporter or a supplier to VAT withholding agents can claim back excess input VAT, the twelve-month limit and how claims are checked.

Some Kenyan businesses end most VAT periods owed money rather than owing it. An exporter whose sales are zero-rated pays VAT on fuel, packaging and services but charges none on what it sells. A contractor whose customer is an appointed VAT withholding agent sees part of the VAT on its invoices withheld before payment. Month after month, the input tax side of the return outruns the output side.
That excess is real money, and for these two kinds of business the law offers a way to get it back in cash rather than waiting for it to be used up. But the route is narrow, it has a strict time limit, and KRA checks claims carefully. This article sets out who qualifies, how to apply and how to prepare a claim that stands up.
When excess input tax becomes refundable
The starting rule in the VAT Act, as published on Kenya Law, is that excess input tax is carried forward to the next period. A refund is the exception. Section 17(5) says the Commissioner refunds an excess that arises from zero-rated supplies, or from tax withheld by appointed withholding agents.
KRA's guidance says the same thing in plainer words: a taxpayer whose input tax exceeds output tax because of zero-rated sales, or because of VAT withheld by appointed agents, can apply for a refund. Otherwise, the excess is carried forward. KRA's frequently asked questions on input tax deduction set out the refund rule and the carry-forward default, and are worth reading before you prepare a first claim.
So the question to ask is not "do we have an excess?" but "why do we have it?" An excess caused by a large equipment purchase in a quiet month, with no zero-rated sales or withholding behind it, is carried forward, not refunded. For the background on each cause, see zero-rated exports and when a customer withholds VAT from your payment.
The twelve-month limit
Both the Act and KRA put a clock on the claim. The VAT Act says the claim must be lodged within twelve months from the date the tax became due and payable, and KRA's guidance gives the same 12 months.
Twelve months sounds generous until you remember how claims are prepared: figures gathered, documents assembled, a first claim audited. An exporter that waits for a year's excess to build up before claiming may find its earliest months already outside the window. A steady rhythm, claiming regularly rather than once a year, keeps every month inside the limit.
Applying on iTax
KRA says refunds are applied for on iTax under the refunds menu. The application gives:
- the bank account details the refund should be paid to;
- the refund type;
- the reason for the claim;
- the amount; and
- supporting documents.
Treat the supporting documents as the heart of the application. For an exporter, that means the evidence behind each zero-rated sale. For a supplier to withholding agents, it means the withholding records and the invoices they relate to.
Pre-payment audits and debt status checks
KRA says all first-time refund claimants are subjected to a pre-payment audit, and that all claims must have valid debt status reports before processing. In practice, a first claim is examined before any money is paid, and any business with unresolved tax debts should expect the claim to stall until the debt position is clear.
The Tax Procedures Act also contains general rules on overpaid tax in section 47. It lets a taxpayer apply to offset overpaid tax against other tax debts or have it refunded, within five years for income tax and within twelve months for any other tax. Under that section the Commissioner must decide within one hundred and twenty days, or one hundred and eighty if the claim is audited, otherwise the application is deemed approved, and must refund within six months of ascertainment. Ask your adviser how these timelines sit alongside the VAT Act's own refund rule for your claim. Income tax refunds follow their own path, covered in claiming an income tax refund from KRA.
Supporting the claim from Achekam's VAT records
A refund claim is only as strong as the returns behind it. In Achekam, a Kenyan tax return is prepared by one person, reviewed by a second and approved by a third. After approval, the return's rule snapshot and figures are frozen, and an amendment is a new version, so nothing is overwritten. When KRA's auditor asks how a month's input tax was arrived at, you can show the approved return as it was filed and any later amendment as a separate version.
If you sell through a till, posted till sales can be listed by VAT rate and tax code for any period, and the VAT return calculations read those posted till sales. For a business with a mix of standard-rated and zero-rated sales at the counter, that listing shows exactly which sales carried 0% in the period under claim.
A refund pack checklist
- The approved VAT returns for each month in the claim.
- A schedule linking the excess to zero-rated sales or withheld VAT.
- Export documents or withholding certificates for every item on the schedule.
- Purchase invoices supporting the input tax claimed.
- Confirmation that the business's debt status is clear.
- The bank account details, matching the account in the business's name.
When carrying forward is the better route
A refund is not always worth chasing. If the excess is small and likely to be used up by output tax in the next period or two, carrying it forward avoids the effort of a claim and, for a first-time claimant, a pre-payment audit. If the excess has no zero-rated or withholding cause, carrying forward is the only route anyway.
Where the excess is persistent and material, a regular, well-documented refund claim is usually the better path. Decide which describes your business, and if it is the second, put the next claim date in the diary well inside the twelve months.
